What causes a freely falling object to stop acclerating and continue to fall at its final velocity?
The answer lies in air resistance, which sets a limit, the so-called terminal velocity, on the speed of a falling object. Air resistance creates drag, a real physical phenomenon associated with objects moving through a fluid. You experience drag riding a bike. Imagine how much drag is on a jet airliner! A boat is affected by drag moving through water. Aerodynamics and hydrodynamics address these issues.

What causes falling objects to reach top velocity?
Falling objects reach top velocity due to the acceleration of gravity pulling them downwards. As the object falls, the force of gravity causes it to accelerate until air resistance (or another opposing force) balances out the acceleration, leading to a constant velocity known as terminal velocity.
How is the initial velocity zero but the acceleration is not?
Going back to definitions, Velocity is change of distance with time; and acceleration is change in velocity with time. Initially, the velocity is zero, as is the acceleration, BUT the Force of Gravity attracts the falling mass, and causes velocity to appear. But the continued application of the Force of Gravity causes the velocity to increase. And as we know, increase in velocity is acceleration. [space for QED]
Why does a falling subjected to earths gravity does not continue to accelerate forever?
what your talking about is terminal velocity, which is when the downward force of gravity (Fg)equals the upward force of drag (Fd). This causes the net force on the object to be zero, resulting in an acceleration of zero
What causes a falling object to reach terminal velocity?
Terminal velocity occurs when the force of gravity pulling an object down is equal to the air resistance pushing up against it. At this point, the object stops accelerating and maintains a constant velocity. This happens when the drag force on the object becomes large enough to balance out the downward force of gravity.

Why do the velocity of free falling bodies not change?
The velocity of free falling bodies does change due to gravity accelerating them towards the ground. However, in the absence of air resistance, the acceleration due to gravity causes the velocity to increase at a constant rate, resulting in a uniform change in speed over time. This creates the perception that the velocity is not changing, but in reality, it is increasing continuously.
How does gravity effect a falling object?
If there is no air resistance, gravity will accelerate the falling object, that is, it will change its velocity.
The point at which an object is falling at the fastest it can go is called its velocity?
When objects fall gravity causes them to increase their speed. The speed would continue to increase if there was no atmosphere. But the atmosphere causes friction which prevents the object from continually increasing its speed. At some point in the fall the object reaches what is called its "terminal velocity". This is the maximum speed it reaches when the frictional force prevents it from going any faster. The terminal velocity of falling objects depends on their shape and mass so it is different for different objects. Also some objects take a long time to reach their terminal velocity so they have to be dropped from very high up in order to have time to reach terminal velocity before hitting the ground.
What causes a falling object to stop accelerating?
A falling object stops accelerating when it reaches its terminal velocity, which is the maximum speed it can reach due to air resistance. At this point, the force of gravity pulling the object downwards is balanced by the force of air resistance pushing upwards, resulting in a constant velocity.
What is meant by terminal velocity of a falling object?
The terminal velocity of a falling object is the constant speed where the force of gravity is equal to the force of drag. Then the forces cancel each other out. Essentially, terminal velocity is when the speed of a falling object is no longer changing. It isn't accelerating or slowing. It's constant.
What causes falling objects to speed up as they fall?
Falling objects speed up due to the acceleration of gravity acting on them. As an object falls, the force of gravity pulls it downward, causing it to accelerate. This acceleration causes the object to increase in speed until it reaches terminal velocity or hits the ground.
What causes variation in velocity of particle?
Variation in velocity of a particle can be caused by external forces acting on the particle, such as gravity or friction. Additionally, changes in direction or acceleration can also lead to changes in velocity. In a vacuum, an object will continue at a constant velocity due to inertia.
